Mongol Posted October 12, 2008 Share Posted October 12, 2008 I bought a new Geforce GTX 280 and HX620 psu last month and have been having a massive problem: The GTX often takes a while to be detected by the Bios and when it is, it is only running at PCI-E x1. It very rarely runs at x16 and will usually change back to x1 after restarting. I have tried many things to fix it, bios updates, options, driver updates, removing/replacing in slot, different slot etc. none of which work. However when I use my old 8800GTS320 it works fine, constantly. The only difference I can see relating to the whole system is that the 280 uses much more power and has two power plugs. Is it possible that the PSU cant supply enough power for the 280 and hence it only runs @ x1 (with very slow performance)? I have already RMA'ed the GTX280 in case that was the source of the problem but they tested it and sent it back saying it was fine, so the PSU is the only other new component. Another small point is that the PSU exhibits an annoying high pitched squeal when using the GTX280 in certain game menus and movies (world in conflict and Stalker clear sky). I'm sure it's coming from the psu as I put my ear right next to it. I've googled the PCI-E problem and read about many people with wildly varying setups having it, a common link in my mind could be a lack of power. Right now i'm at a loss so any help is appreciated. Ps. If I do have to RMA the PSU do I have to post it to the USA? That would cost about half what it paid for it so not the best solution. Link to comment Share on other sites More sharing options...
